I would like to have the reverse. I would like to keep the newlines and replace any \n in the file with a comma.
xbin told you already (the more important) half of the truth, here is the rest of it:
"\n" has a special meaning to sed, in fact it means "newline character". Whenever you have to deal with a character with a special meaning to sed you can strip it of its special meaning by prepending a "\" to it: "\*" will not mean "zero or more of the previous character" but "literal asterisk". The same is true for "\\", which will mean a literal backslash. This mechanism is called "escaping". Hence:
Dear all

etc

Hi All,
I have some 50,000 HTML files in a directory. The problem is; some HTML files are duplicate versions that is wget crawled them two times and gave them file names by appending 1, 2, 3 etc after each crawl. For example, if the file index.html has been crawled several times, it has been... (1 Reply)
Hi all,
I wrote the following code to remove the value which are 0 in the input file (a columns if numbers).

MakeMethods::Utility::TextBuilder(3pm) User Contributed Perl Documentation MakeMethods::Utility::TextBuilder(3pm)NAME
Class::MakeMethods::Utility::TextBuilder - Basic text substitutions
SYNOPSIS
print text_builder( $base_text, @exprs )
DESCRIPTION
This module provides a single function, which implements a simple "text macro" mechanism for assembling templated text strings.
$expanded_text = text_builder( $base_text, @exprs )
Returns a modified copy of $base_text using rules from the @exprs list.
The @exprs list may contain any of the following:
o A string, in which any '*' characters will be replaced by the base text. The interpolated string then replaces the base text.
o A code-ref, which will be called with the base text as its only argument. The result of that call then replaces the base text.
o A hash-ref, which will be added to the substitution hash used in the second pass, below.
o An array-ref, containing additional expressions to be treated as above.
After any initial string and code-ref rules have been applied, the hash of substitution rules are applied.
The text will be searched for occurances of the keys of the substitution hash, which will be modified based on the corresponding value in
the hash. If the substitution key ends with '{}', the search will also match a balanced block of braces, and that value will also be used
in the substitution.
The hash-ref may contain the following types of rules:
o 'string' => 'string'
Occurances of the first string are to be replaced by the second.
o 'string' => code_ref
Occurances of the string are to be replaced by the results of calling the subroutine with no arguments.
o 'string{}' => 'string'
Occurances of the first string and subsequent block of braces are replaced by a copy of the second string in which any '*' characters
have first been replaced by the contents of the brace block.
o 'string{}' => code_ref
Occurances of the string and subsequent block of braces are replaced by the results of calling the subroutine with the contents of the
brace block as its only argument.
o 'string{}' => hash_ref
Occurances of the string and subsequent block of braces are replaced by using the contents of the brace block as a key into the
provided hash-ref.
EXAMPLE
The following text and modification rules provides a skeleton for a collection letter:
my $letter = "You owe us AMOUNT. Please pay up!
" .
"THREAT{SEVERITY}";
my @exprs = (
"Dear NAMEm
*",
"*
-- The Management",
{ 'THREAT{}' => { 'good'=>'Please?', 'bad'=>'Or else!' } },
" DATE
*",
{ 'DATE' => 'Tuesday, April 1, 2001' },
);
One might invoke this template by providing additional data for a given instance and calling the text_builder function:
my $item = { 'NAME'=>'John', 'AMOUNT'=>'200 camels', 'SEVERITY'=>'bad' };
print text_builder( $letter, @exprs, $item );
The resulting output is shown below:
Tuesday, April 1, 2001
Dear John,
You owe us 200 camels. Please pay up!
Or else!
-- The Management
